Everything you need to know about generating comp titles and query letters with SynopsisGenie.
SynopsisGenie is an AI-powered tool that helps authors generate market-ready comparison (comp) titles and professional query letters for literary agents. You provide your book's summary, age demographic, and genre, and the tool produces a polished starting point you can refine.
Comp titles show agents that you understand where your book fits in the current market. By referencing recently published, comparable books, you signal that your project is commercially viable and that you've done your research. Agents use comp titles to quickly gauge your book's audience and positioning.
Every visitor gets 3 free generations. Once you've used them, a 24-hour cooldown begins before your free uses reset. If you need more right away, you can purchase a Day Pass for $5, which gives you unlimited generations for 24 hours.
A Day Pass costs $5 and unlocks unlimited comp title and query letter generations for 24 hours. After purchasing, your usage counter resets immediately and stays unlimited until the pass expires. Payment is processed securely through Stripe.
No account is required to use SynopsisGenie. Your usage is tracked locally in your browser, and you can generate comp titles and query letters anonymously. If you'd like your results emailed to you, you can sign in and use the email-me feature.
They're designed to be a strong starting point, but you should always review, edit, and personalize the output before submitting. Verify all book details (titles, authors, publication dates) and follow each agent's specific submission guidelines. AI-generated content is for brainstorming and drafting, not final submission.
Our agent recommendations come from a manually curated, hand-vetted database that is updated every six months. We match agents to your genre and age demographic. For privacy and accuracy, we only list agent names and agencies — never contact information. Always verify an agent's current submission policy on their agency website before querying.
Your generations are saved locally in your browser so you can revisit them later. We don't share your content with third parties. You can clear your entire generation history at any time using the Clear button.
SynopsisGenie also offers a Reading Time Calculator, Chapter Length Calculator, Novel Progress Tracker, and Character Name Generator, plus free educational guides on word counts, raising story stakes, writing fight scenes, and crafting query letters.
